A card storage space S for storing 21 is configured. Six contacts are arranged in the bottom plate portion 111a in the insertion direction A and the removal direction B at predetermined intervals. Card 1
As shown in FIG. 6, the contact 21 has a contact 11 on one side.
3 is provided with a card contact portion 121a that makes a one-to-one contact.

Each of the plurality of contacts 113 extends from the holding portion 113a held by the bottom plate portion 111a of the insulator 111 to the inserting direction A and the removing direction B from one end side of the holding portion 113a and in the plate thickness direction of the card 121. A spring portion 113b that is deformable to C and a terminal portion 113 that extends from the other end of the holding portion 113a to the outside of the insulator 111 and is connected to a conductive portion (not shown) provided on the substrate.
c and.

A contact portion (not shown) is formed at the tip of the spring portion 113b so as to project into the card housing space S and contact the plurality of card contact portions 121a in a one-to-one relationship. An elongated hole 111g is formed in the bottom plate portion 111a so that the spring portion 113b can be deformed in the thickness direction C of the card 121. The spring portion 113b is located in the long hole 111g.

To mount the card connecting connector 101 on the board, the insulators 111 and the contacts 113 are mounted.
After assembling, the terminal portion 113c is soldered to the conductive portion of the substrate by soldering such as reflow soldering.

The contact portion of the contact 113 is the spring portion 11.
Since the card 121 is inserted in the insertion direction A and extends in the same direction as 3b, when the card 121 is inserted and accommodated in a predetermined position of the card accommodation space S, the card contact portion 121a of the card 121 is attached to the contact portion. Contact one to one.

As described above, according to the present invention, when the main plate portion faces the substrate and the insulator is mounted on the substrate, the guide portion of the contact projects into the card accommodation space. Since it is inserted into the card accommodating space, the height dimension of the insulator can be reduced, and an optimum card connecting connector can be provided for mounting a device that is small and thin.
That is, since the insulator does not need a plate portion on the substrate side, it is possible to reduce the height of the card connecting connector itself when the insulator is mounted on the substrate.

Further, since the card is inserted in the insertion direction from a direction substantially perpendicular to the contact spring portion, the card can be smoothly inserted in the insertion direction by the guide portion having a long dimension in the insertion direction.
